CORRECTED VERSION 2026-03 IEC 63563-7:2025 defines methods for ensuring that the power transfer proceeds without heating metal objects in the magnetic field of a Power Transmitter. Although the Power Transmitter may optionally use any of these methods, some of them require assistance by the Power Receiver. This corrected version of IEC 63563-7:2025 incorporates the following correction: - correction of the publication date on the cover page.

Overview

IEC 63563-7:2025 - Qi Specification version 2.0, Part 7: Foreign Object Detection (FOD) - defines methods to ensure wireless power transfer proceeds without heating metal objects in the magnetic field of a Power Transmitter. Published by IEC and based on the Wireless Power Consortium (WPC) Qi Specification v2.0, this standard describes optional and mandatory-convention methods for detecting foreign objects; some methods require assistance from the Power Receiver.

Keywords: IEC 63563-7:2025, Qi Specification v2.0, Foreign Object Detection, FOD, wireless power, wireless charging.

Key technical topics and requirements

Scope and compliance model:

The specification is part of the Qi family and follows IEC/ISO directive conventions. Provisions use standard verbal forms (e.g., shall, should, may) for requirements and recommendations.

FOD method families covered:

Pre-power transfer FOD methods: tests performed before power delivery begins, such as the empty surface test and resonance change detection.
In-power transfer FOD methods: continuous or calibrated monitoring during power transfer, including basic power loss accounting and calibrated power loss accounting.

Representative and test methods:

The document identifies representative foreign objects and prescribes approaches for determining reference FOD values (normative Annex A).
An informative Open-air Q test (Annex B) explains measuring the quality factor (Q), Q-deflection, threshold selection, temperature compensation, and practical test flow for assessing FOD sensitivity.

Implementation notes:

Methods are optional for transmitters; some require receiver cooperation for measurement or calibration.
The standard emphasizes correct application of referenced documents and that numeric values have no implied tolerances unless specified.

Practical applications

Ensures safety and performance for wireless charging pads, smartphone chargers, in-vehicle wireless power modules, and other flat-surface wireless power products (Baseline and Extended Power Profiles).

Prevents heating of metal objects (coins, keys, tools) on or near transmitters by detecting and reacting to foreign-object conditions.

Supports design choices for transmitter control logic, FOD algorithms, and test procedures used during product development and certification.

Who should use this standard

Product designers and hardware engineers for wireless power transmitters and receivers

Test engineers and compliance laboratories performing FOD testing

Safety and certification teams validating wireless chargers against Qi/FOD requirements

Manufacturers implementing Qi Specification v2.0 features (power delivery, communications, thermal/mechanical integration)
